i was wondering if anybody has experienced a wicked vibration on a 3.8 with manual trans. it does it when you go up from idle or let off to idle while the car is sitting.(does no have to be moving/driving for vibration). i thought it was the mounts, so i changed both motor and the tranny mounts, it lessened but did not go away. i was flipping through some of the papers the guy i bought the car from gave me, there was a estimate for a flywheel, would a bad flywheel cause this? thanks for any info in advance.
